Are you looking for a way to print with endless colored ink on a budget? This printing trick is one of the best things that ever happened to me as a teacher! - this sounds interesting but we would need to buy a new printer
(via Team Vs First Grade Fun: Im Done Cups) Students pick a stick from the Im Done cup and work on an activity when they are finished with their work. Teachers can range the activities depending on the grade.
The way it works is that when I need the class to quiet down, I start counting backwards from five: If I get to and there is even one student talking, I get the tally point. If the entire class is quiet, they get the point.
